4656EA-021 ebmpapst 230V 19/18W AC Axial Fan

Description

The ebmpapst 4656EA-021 is a high-performance AC Axial Fan with dimensions of 110 x 39 mm. This premium fan operates on a nominal 230 VAC supply and is distinguished by its “Full Metal” construction, utilizing a die-cast aluminum housing and a sheet steel impeller for maximum heat resistance and structural rigidity. Delivering a maximum airflow of 105.9 CFM (180 m³/h) at 60 Hz, it is equipped with a high-endurance ball bearing system and an external rotor motor with an output power up to 5.4 W. This model is specifically engineered for high-stress industrial environments, such as power electronics and telecommunications, where it provides superior reliability, IP20 protection, and consistent performance across a wide operating temperature range from -40 °C to +85 °C.

Application
The 4656EA-021 is specialized for extreme-duty industrial cooling where plastic components are unsuitable due to high ambient temperatures or mechanical stress. Its all-metal design makes it ideal for use in industrial ovens, large-scale motor drives, and high-capacity power distribution units (PDU). The ball bearing system allows for installation in any orientation, making it a versatile choice for rack-mounted IT infrastructure, professional stage lighting, and telecommunications base stations. With its wide operating temperature range and robust external rotor motor, it ensures mission-critical cooling in environments ranging from sub-zero outdoor cabinets to high-heat industrial processing plants.
